Application filed' October 12,1921. Serial No. 507,227.

To aZZ whom it may concern:

Be it known that I, ADoLPHUs H. LANDRY, a citizen of the United States, and a resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Picker Motion, of which the following is a description.

The general object of my invention is to provide a new picker motion in which various features of the picker means now employed are done away with whereby to simplify the construction and to make for pre cision in the operation of the picker staff.

The nature of the invention and its distinctive features and characteristics will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this'specification, it being understood that the drawings are merely illustrative of two examples of the invention.

Figure 1 is a side elevation of a picker motion embodying my invention;

Figure 2 is a horizontal section on the line 2-2, Figure 1;

Figure 3 is a View similar to Figure 1 but illustrating a modification;

Figure 4 is a horizontal section on the line H, Figure 3.

Referring at first more particularly to Figures 1 and 2, the numeral 10 indicates conventionally a fixed frame part of the loom, 11, the lay associated with which is a picker staff 12, said picker staff being pivotally secured at one end by a bolt 13 or the like to a holder 14: pivoted by a bolt 15 or its equivalent to an element 16 positioned similarly to the usual rocker and mounted on the frame element 10.

Spring means is provided tending to restore the picker staff 12 after a forward movement about the axis of the bolt 15 as a center. Said means in the form shown in Figures 1 and 2, consists of a spring 17 coiled about an elongated rod 18 extending approximately parallel with the picker staff 12, said rod having thereon a collar or enlargement 19 tapered to seat in a notch 20 in the laterally disposed lower terminal of the holder 14. The upper end of the spring 17 abuts against a collar 21 threaded onto the rod 18 to vary the tension of the spring.

The upper end of the rod 18 extends through a fixed lug 22 on the lay 11 and beneath said lug is a set collar 23 on the rod 18, said collar having a \l-shaped protuberance 24: entering a corresponding notch in the under surface of the lug 22. The spring 17 serves to restore the picker staff 12 after. a forward movement thereof.

A forward movement is imparted to the picker stafi 12 in the form shown in Figures 1 and 2, as follows: On the staff supporting element 16 is a head 25 having a vertical slot 26 and a transverse bolt 27 passes through said slot and through the lower end of a lever 28, which extends longitudinally of and adjacent to the picker staff 12, the upper end of said lever being pivotally secured by a bolt 29 or the like to a transversely disposed operating element 30 having the general position and function of a sweep but not involving the use of a strap, it being understood that said element 30 has movement corresponding with the usual sweep for operating the lever 28 to actuate the picker staff 12 for throwing the shuttle. The bolt 27 permits of vertically adjusting the fulcrum point of the lever to vary the point of contact with the picker staff 12 and thereby vary the leverage exerted on said picker staff. Similarly, the connection between the operating device 30 and the lever 28 may be varied by provision of a plurality of bolt holes 31 in said element 80, either one of which may receive the bolt 29. The form shown in Figures 3 and 4 shows the adaptation of the device to a different form of loom having a known form of arm 32 for acting on the operating element 30*. The lever 28 and bolt 29 correspond with the arrangement of Figures 1 and 2, the fulcrum 27 of said lever passing through a vertical slot 26 on a bracket 25 formed on a rocker 15*- formed on a holder 14 secured by a transverse bolt 13 to the picker stafi 12 The rocker 15 is supported on the outer end of the element 16 corresponding with the element 16 positioned to correspond with the usual rocker of a known picker motion. The rocker 15 of the holder 1 1 rests at one end on a coil spring 17 which is supported on a seat 19 rigi with the element 16 there being a bolt 18 passing through the rocker 15 spring 17, and seat 19 and tending to restore the picker staff 12 after a shuttle actuating movement.

The parts of the above-described picker motion including the picker staff, I form from suitable metal, preferably the metal known as magna metal which is exceedingly light.

I would state in conclusion that while the illustrated examples constitute practical embodiments of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied Without departure from the spirit of the invention as de ed in the appended claim. 7

Having thus described my invention, I

claim ADOLPHUS H. LANDRY.
